I am a chronic disease and genetic epidemiologist with an interest in identifying novel causal pathways and new therapeutic targets for reducing risk of chronic diseases. Since March 2018, I have been working as a Research Associate in the Stroke Research Group in the Department of Clinical Neurosciences. My current research primarily focuses on utilising epidemiological, clinical, genetic, and imaging data to investigate relationships between vascular risk, stroke, and dementia. Specific projects that I have been involved in include identifying (1) the role of haematological traits in risk of stroke and its subtypes, and (2) the association of metabolites with imaging markers of SVD, cognition, and dementia.
